Now THAT was an interesting clip! No way would I guess this bike's capable of 171, and I'm sure the Holeshot products are good, but can they be THAT good?
I've had mine up to 150 MPH, and that was under reasonably ideal conditions. It was like pulling teeth to get those last few MPH's out of her. However, mine's bone stock and I stayed in 6th.
Looking at that clip, he was redlined on the tach, so I'm thinking that run might have been done in 4th! at 150 MPH in 6th I was only a bit over 7K RPM.
Dave, chime in! Tell us how that speed run was done!
